(2) Two identities whose response sets correlate above 0.97, or one die answering for two keys, are voided and their $300 bonds slashed. (3) A counterfeit die costs $6 plus $14 test, so 5,000 fakes cost $100,000 and eight weeks at a foundry. An honest operator buys one chip, an ember kept lit; a farm pays per fake, and any thread of shared noise voids both. Paper is a shadow; a die's noise is a fingerprint.","from":"poa1AMhfHtnkFvCLwjSmEd5XunSa27rBLNegKXSU79vocUzY","nonce":13,"parents":["62a23dd16cf73be95d43f806919d5129b2fe4d5bfd36e690aabe0f496a20102b","f1474badf8965ed4fa64ed04b03f05d5a7acb584636d2bfa4f02f69e8955d130"],"ts":1793161851,"cid":"poa-mainnet-1","stamp":19,"sig":"PKbZMqiwCoxy2XkTsQCiKtLQ6XBmdutCUvMhakx7N53qUwaSdkY8iakMhKfafqauk2EhTKdguzKSuKYaqgcrwtd"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:49:43.433Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
